Noiseless-without smell PVC tank-eliminating dirt due to rust Contains one thermal circuit breaker. Available power; 5kw, 10kw and 15kw Economical, this model is designed for indoor or outdoor installation. However, it is strongly recommended to install the heater inside or out of the sun exposure. Designed for above ground pools or built-in pools with 15000 gallons capacity. CSA approved. One year warranty on all parts except heating elements. WARNING As like all pool heaters, VAL THERM must be filled of water when in operation. Risk of damage when used dry. Such damage is not covered by the warranty. Install heater below water level to ensure of a full tank. It is strongly recommended to install inside or out of the sun exposure. For safety purpose, the installation of your heater should always be done by a qualified electrician. Maintain proper water chemical balance: ph level: 7.2-7.6, Alkalinity: 80-140, salinity: 180-260, otherwise internal parts may deteriorate prematurely, those damages are not covered by the warranty.

HOW TO DERTERMINIE THE RIGHT POWER RATING OF YOUR VAL THERM POOL HEATER The following factors will influence the power needed for your pool heater: Pool dimension, average depth, wind exposure, period of utilization, ground composition, weather, etc... With normal weather conditions as in our regions, we will be able to determine the power needed for your pool heater, based on empirical method or mathematical formulas. EMPIRICAL METHOD Our experience shows that according to your utilization period, the power of your heater should be as follow: 4 months utilization: 1.0 kw per 4500 litres (1000 imperial gallons) 5 months utilization: 1.5 kw per 4500 litres (1000 imperial gallons) 6 months utilization: 2.5 kw per 4500 litres (1000 imperial gallons) MATHEMATICAL METHOD You can determine your heater power and also weather elevation rate for a given heater by applying this formula: How to establish the heater power: Power (KW) = K (W/ Cft²) X temp.diff. ( C) X surf pool. (pi²) 1000 (W/KW) K: Conversion constant: 5.715 W/ ft² Temp. Diff.: Temperature spread between water surface and ambient air. Normal use is generally between 5 C and 8 C. How to determine temperature elevation rate: Elevation ( C/hour) = K ( Cft³/KWH) X Power (KW) Surf. pool (ft²) X av.depth (ft) K: VAL THERM POOL HEATER
Rule of thumb: for each KW per 1000 gallons of water, you can add 1 F of temperature elevation an hour.

The above figure can be used when difference in temperature between the water and the ambient air is 1 C. However, if that difference is more than 2 C, then the rate is higher than those shown on the figure. This is due to the loss of heat that the heater has to compensate before effectively increasing the temperature of the water.

HOW TO DETERMINE THE COST OF THE VAL-THERM POOL HEATER Formula : proposed KW X n Hours of operation X cost kwh* *kwh = kw X hours (consumption inn kilowatthour) Example: if the required pool heater power is 10kw. In operation for 10 hours/days, and the cost per kwh is 5.88 (1997 domestic rate in Quebec). Then the daily cost would be: = 10Kw X 10 hours/day X 5.88 = 100 X 5.88 /kwh = 5.88$ per day INSTATALLATION - LOCATION SITE This Val Therm, water heater can be installed either. However, we strongly recommend installing the pool heater inside. It is important that all safety and installation standards be respected. The water heater must be positioned vertically at the filter end. Free space of left space of about 18 on top of it should be left for maintenance purpose. When installing, it is recommended to install a bypass. The connection of the plumbing must be install by professional. STAR UP 1- Before switching on pool heater, activate the pump of the filter and ensure that no air remains inside the water heater. This can be checked when no more bubbles appear at the pool when water recycles back to the surface. 2- Adjust the thermostat to the desired temperature level. The time to reach the desired temperature varies, depending on initial temperature of the water, weather conditions, etc... For security, one reset button protect the machine against high temperature elevation 120 C, the reset button shot off automatically the circuit, so you have to restart by pushing the red button. The second security, It s a pressure switch for the lower water pressure in the water thank. This unit require a minimum flow of 35 gallons per minute. 3- Maintain proper water chemical balance: ph level: 7.2-7.6, alkalinity: 80-140, salinity: 180-260, otherwise internal parts may deteriorate prematurely, those damages are bit covered by the warranty. 4- Tank should be full of water before starting up, otherwise permanent damage to parts occurs. Such damage is not covered by the warranty. PLUMBING The inlet and outlet of the pool heater are connected to two 1 ½ N.P.T. threaded cap is included with all models for emptying convenience. Note: Use only Teflon tape to assure water tightness of pipes connections. Be careful not to over TITS the fitting because it can crack-will not be cover by warranty

DÉVIATION OPENED VALVE Water inlet Water outlet CLOSED VALVE CLOSED VALVE It is recommended to isolate your water heater on the water by pass when you do your shock treatment at the opening of you pool not to damage the component.
WINTERIWING Empty heater tank draining plug to prevent water freezing inside tank during winter. SAFETY Before opening the pool heater, make sure it is not plugged in. This unit require a minimum flow of 35 gallons per minute. Part replacement with original only Do not install two heaters on the same line because it could lower the water pressure and cause damage. If water stays cold and pilot light is off: 1- Check the voltage TROUBLESHOOTING 2- Check circuit breaker, main fuses and replace if necessary 3- Check the High Temperature Cut-off Switch with Manual Reset (refer to the physical diagram). 4- Check thermostat. If water does not heat as wanted and pilot light is on: 1- Check voltage 2- Check thermostat 3- Check heating elements.
